whenever there is price drop there are only two scenarios:

1) things become volatile and continue to be that way, and it can even go lower. so buying is not suggested in this case

2) you see a bottom and a very excellent price to buy at, a price that wouldn't be possible without that drop. so buying is highly recommended in this case.

the scenario #2 is always followed by #1 and you should know that going down doesn't last forever because we are talking about bitcoin not a failed altcoin here.

you should say what you want to do, as in what is your plan when making this investment. if you are planning on making some short term profit and sell as soon as possible it is different than if you want to make a long term investment.

for the later it is good for buying now, but for the former you have to be careful after you buy because price can go up or down in short term but long is sure.

that was pretty funny.
but i gotta say, someone who is idiot enough to use a third party for his bitcoin wallet instead of running a full node or at least use a desktop wallet ....
and not to mention someone who is idiot enough to use a freaking US based service as his wallet... i mean they record and report everything without any hesitation, even if they say they don't they are reporting everything at least to IRS.

deserves to go beside Jail nigga and be cell mates.

in my opinion it is because how exchanges are like today.
there is an orderbook which is still thin and because of that a whale can cause panic and others join in when they see the opportunity and sell to help the panic then they buy back at the bottom.

you see, traders who are only thinking about more fiat love a volatile market and the more swings it has and the bigger they are the more they can earn.

if those who bought bitcoin stop listening to fake news and stop giving their coins to the whales buy orders price won't swing this much.

what does anything you said have to do with anything else here?!

OP has a transaction that has a low fee (by the current standard of the fee market battle) and that is why he is getting a low priority to be included in a block.

you say two things here:
- double spend, has nothing to do with how slow or fast you get a confirmation.
- your red text of "status coinbase" show the status of the site coinbase which shows if it is online or offline! again has nothing to do with either double spend or with low fees and fast confirmation.

back in 2015 when price was crashing to $200 and even once it went down to $170 everybody were desperate and thinking price can never go up again. i said it back then and i say it again here, it is just a hiccup, a bump on the road. we will get back on the real track soon, as long as regular holders stop giving their money to whales for free or whales feel like their pockets are full enough.

we are the ones who are giving the news power, it really doesn't have that kind of power. if we stop clicking on the news sites which have crappy click bait articles they won't get as much traffic and the rank goes to places that have better honest articles.
and in time news like this that are fully FUD can no longer affect price at this magnitude.

this has nothing to do with bitcoin or its price, it is regulation and it should have happened a long time ago, it is just bad timing. and it has been happening in the US and now it is happening in China and will continue in other countries.

whenever you do a business in any country and handle lots of money you have to be regulated and have license that is not a new thing and not a bitcoin thing either.

the fact that bitcoin price is going down is because there are many whales who take this opportunity to make a lot of money from weak hands.

the reason is only one word: PANIC

there is nothing going on. the news you keep hearing is an exaggerated versions of what is happening like bitstamp being inaccessible or China banning bitcoin,...

people these days are so fast on clicking sell than they are on using their brains/

here is a list of them: http://coinmarketcap.com/currencies/bitcoin/#markets
the famous places are those with highest trade volume (mostly bitstamp and bifinex).
and i don't know what you mean by pays quickly, you deposit an amount on the site (fiat or cryptocurrency) and then trade as fast as clicking can be. and withdrawing and depositing cryptocurrency is fast but money may take some time since it has to go through a bank

instead of all this and wasting money start a business with a lot less than what you are suggesting.
for example starting a website like Amazon or ebay is not going to const 100BTC but the effect of it can be bigger than any advertisement you can do.

Thanks for the payment.

just a reminder: please upgrade my rank in spreadsheet to Hero ^.^

also i always like to remind people that Dogecoin has a couple of billion coins available which means a massive supply and in other words the current Doge price is even over-priced!

all of these can essentially affect bitcoin price too.
we have seen many times that economy has had its effect on bitcoin when people started investing their money in bitcoin to escape their country's bad economy.

but the biggest effect goes to adoption. since bitcoin is still a new technology as time passes and more people start to find out about bitcoin, put away their fear and use their brain to see the benefits of bitcoin they start buying it and with a limited supply price will go up.

not so near but we will surely see $1300 and possibly a lot more this year.

i agree that things are so different from 2013-14 and the massive bubble we witnessed in bitcoin. and this time the rise took its sweet time before getting to the current price and since it has been strong it can not go wrong thing time around.

i say they both were effective but not enough for such a rise specially India since the trade volume on their exchanges weren't that high and only localbitcoins were reporting a rise in the volume (which wasn't considerable compared to others).
and that 50K limit in China i don't think is going to show its effect on "bitcoin price" right away because those merchants who want to deal with more than 50K are not going to jump into bitcoin as soon as they hear this news.

well $600 is impossible, period.
the "dump" also proved this.

before the rise happened (bubble of 2016 $1150) price was strongly holding at $780 with a strong buy support. and after the dump happened price couldn't break $800 and that is a good sign.
another good sign is that price is currently at above $900 once again so the buy support is still there.

as long as there are miners mining both chains (forks) and nodes holding both chains they both will exist and since there will be two blockchains you will have coins on both of them.

and this is actually one of the reasons why consensus is 95%

for an example you can check what happened with ethereum hard fork, they did it without consensus and ended up with two chains called ETH and ETC with people having coin on both chains.

if you are calculating things in general the math that xhomerx10 did is more or less true but if you are talking about certain farms specially the Chinese farms things are so different.
- Electricity costs you see on the internet is an average for average people  miners have special contracts with electricity providers which makes it even cheaper.
- the mining equipment is built in China, they have access to it directly and they also have special contracts to get them cheaper.

these two alone break all the equations.

your best option is to find an exchange in your own country to exchange bitcoin/altcoins for fiat there because it will be easy and will be much cheaper than any other options.
since you live in Hong Kong you may find the Chinese board here (https://bitcointalk.org/index.php?board=30.0) more helpful to your situation since you can find others there.

the demand for fiat will always exist as long as we are living in a country with a government and majority of its citizens using fiat. and besides the only place that i have been seeing people talk shit about fiat and banks is here and even those who do, are using both fiat and banks with open arms. so there really is no way to see the demand for fiat be reduced at all.

you can look at a chart and find that out yourself.
but as far as i can tell there is no specific month when it happens.
right now, wait for the volatility to stop and you can see an stable price again in a short time.
why would you want an stable price to buy? if you plan on hodling then buy now and if you play on day trading then again buy now! in both cases you can make profit!

i can only tell you that it will stablize somewhere between $800 and $999

nobody told you that, you read it on a topic or a click-bait-news-site. and what you read is called FUD

did you see his face and knew he is Chinese
and some other guy bought 10,000BTC on the value of $1150 USD =b 1 bitcoin what is your point?
